The lower leg 34 e`x tends forward beyond the front face of the stop bar 30 and is provided at its upper edge with a notch 37 which receives a locking bar 38 that is mounted on the front of the step bar 30 being provided near its ends with cam slcts 39 which receive headed screws 40 that are secured in the front face of the stop bar. The right-hand end of the locking bar is turned outward to provide a finger piece 4l by which the bar may be pushed endwise for locking and unlocking purposes. When the bar 38 is pushed rightward.. the slots 39, cooperating with the Shanks of the screws 40, will force it upward and out of the notches 37,

the stop barl and re-adj usted thereon. Normally the locking bar cooperates with the nctches 37 to hold the column stops securely in adjusted positions. As stated, the column stops are generally alike, but they ditl'er from each other in that each is provided with a rearward projection, lugor stop proper and these projectie is are :E: different heights for the different stops. Thus inthe present instance. as appears from Fig4 1. the stop lug 32a of thel column ,stop 32 a1 Vanged at the extreme left of the series, is at the top of said column stop while the stop lug 32e ofy the right-hand column stop is at the lower end of the associate column `stop and the stop lugs 32, 32 and 32" of the intermediate column stops are in horizontal planes between the lugs 32"1 and 32e, these planes being successively lower than the plane ot' the upper stop lug.. In other words, the stop lugs are arranged in a series 'of steps at progressively varying heights.

To coperate with the stop lugs or column stops proper above described are a set of frame stops, ive in number, one foreach of the'column`stops. Sald frame stops, in

x the present instance.- are o't novel construc- "tion, being in the form of plate-hlre bars orkstop levers 42 arranged in tiers on top of each other and relatively movable or swingable in horizontal planes fore and aft of the machine about a commen axis or pivot pin 43 but independently of each other.

Said `stop levers 42 are arranged between the upper and Ilower walls 44 of the head 45 of a stop frame 46 which is detachably secured to the main frame of the machine by means comprising screws 46a (Fig. l)

construction of the tabulator stop frame of the No. 11 Remington typewriting machine. The detail features of the stop levers and the manner of mounting the same are best illus;

trated in Figs. `3 to 5.

The upright pivot pin 43 on which the stop levers or arms are piveted is arranged near the right-hand 'ends of said levers, which are generally thus enabling the column stops to be removed from *srwe vertical in the front faces of the levers or arms 42A are of a width sufficient to receive between their walls the column stop lugs and the lefthand wall of each nctch is inclined as indicated at 48 oppositely from the inclined face 49 of a lug or extension which projects orward from the general vertical plane of the forward sides of the stop levers or arms 42. The tip or front end of the lug 50 is blunt, being normally parallel with the rear edges of the column stop lugs and slightly in rear of the same so that only av short forward swing is required to bring said lugs into the paths ot their cooperating stop lugs on the carriage. Leftward from the blunt tip of the lug 50 it inclines rearabove the other in the rear wallfof the head 45 at the right-hand sidethereof. These springs cooperate with the rear edges or faces of their associate stop 'levers 42 at the right of the pivot 43 and operate to swing the left-handl parts of said levers rearward and to maintain them normally engagedwith the left-hand portion 54 of the rear wall of the head 45.

' In order to overcome the springs 52 and project the levers 42 forward into the path of the column stops, "devices are provided comprising upright levers 55 arranged between the side walls of the frame 46, said levers 55 being provided with slots 56 which coperate with a transverse fulcrum pin 57 supported on said `trame. A locking pin 58 forward of the fulcruin pin 57, cooperates with the levers 55, to prevent accidental displacement from said fulcrum pm. At their upper ends the levers 55 are brought closev together in parallel vertical planes at right angles to the planes of the ,stop levers 42 and are curved or bent forward, terminating. These.4

fingers are stepped orarranged in progresplanes, there being one finger opposite each fa ce of each of the stop levers 42` the finger 59 of the left-hand lever 55 being highest and opposite the uppermost es, 1i 'l'le au aged bj one @1119253 of l render le s; E so mi wh @whom but L Vd 1x: rzflmw mddle mm in H1@ set in the vymfirst column stop having the lug 32 which coperates with the projected stop lever. Assuming the carriage to be at the right when the first or left-hand column selecting key .72 is actuated to. project the uppermost stop lever 42 and release the carriage, said sure exerted on the key 72, there being enough resiliency and give in the parts between said key and the stop lever to permit such backward camming ot' said lever without appreciablyl affecting the key. As soon as the stop lug 32 enters the notch 47 the stop lever will snap forward until arrested by the contact of the bottom of the notch with the rear face of the lug 32a. The parts at this time will be in the position illustrated in Fig. 4. The stop lug 32, it will be observed, is embraced between the walls of the notch 47 and the left-hand face of the stop lug 32a' is in contact with the face 49 of the lug 50, which face acts as an arresting device. If the key 72 he now released the operated parts-will return to normal position, theV return movement of the stop lever 42 being assisted by the camming action exerted by the lug 32u on the edge 49, which edge, as the stop lever swings rearward, will in- Cline more and more at au angle to the fore iand aft plane containing the left-hand face v of the lug 32h. A similar action of the parts will take place at each following column selecting operation during therun of the carriage from left to right.

With the carriage at the left, if it be vde. sired to arrest it at any desired column durl ing the return movement, the operator, as

before, depresses the desired column key 72, projecting the associate stop lever 42 and releasing the carriage. The carriage, however, is restrained from moving toward the left by the disengaged hand of the operator who pushes the carriage against the pull of the motor back toward the right. This brings the stop lug of the selected column stop into engagement with the cam 4device or face 51 of the projected stop lever'42, said lug coperating with said face to cam or force the lever 42 rearward until the stop lunr y is Lbrought opposite the notch 47 whereupon the stop lever 42 will snap forward and the notch will embrace the sides of the sto as in F ig. 4, the right-hand wall of the notch acting as an arresting device. The'parts are then released. The timing is such that be-` fore the locking notch frees the column stop the feed rack 1G will have engaged with the feed pinion, thus restoring the carriage to passes over the point of the` lug 50 andl lug the control of the escapement devices. Thereafter the entry in the column is written as in ordinary rlght to left tabulating or column selecting. The above described operation is repeated each time it is desired to eil'ect a reverse tabulating or column selecting operation. Reverse tabulating or column selecting operations may be conveniently employed in listing work, for example, as the operator, after writing one of the items on the list merely actuates the proper column selecting or tabulator key 72 and line spaces the paper, at the same time pushing the carriage toward the right until it is ar'- rested by one of the stop levers engaging with the associate column stop. Such arrest brings the carriage in position for writing the next item on the list under the item previously written. Considerable time is thereby saved, since if tabulating in the usual way were continued, the operator would, after writing in one item, pull the carriage rightward to the limit of its movement and then actuate the column key, causing the carriage to run toward the left until arrested, thus resulting in an unnecessary repetition of movement which is avoided by reverse tabulating in the manner described. It will be observed that by my present invention I provide for tabulating or column selecting either in the usual way or in the Vreverse direction at will and without any change or re-adjustment or re-settmg of.

any of the parts. rl"he only difference between the two kinds of operationsis that in reverse tabulating the operator pushes the carriage back against the pull of the carriage motor until it is arrested. It is further to be noted that the positionof arrest 42 are enabled to be cammed or swung back- 'ward preliminary to the snapping in or locking engagement of said levers with the column stops an dsuch camming movement would be ditlicult if not practically impossible with stops pivoted to swing in vertical I planes on an axis parallel with the line of carriage movement. Then too, the disposition of the notch wall- 49 enables the stop 42 to be cammed quickly out of the way by the force `exerted-by the carriage motor when the columnkey is released.
